6 Claims. (Cl. 206-'56) This invention relates to a lipstick devicea'nd 'more particularly to a novelcarrie'r employedftherein.

Heretofore,k lipstick devices have' been provided with an inner'cylindrical member having one or more `longitudinal 'slots in which a lipstick carrier havingpinsprojecting through the slot is -moved by means of a rotary sleeve member mounted on the inner'member for rotation with yre'spect'thereto and having one or more helical grooves "for |receiving the pins to"`advance" or retract the lipstick carrier in uresponse to said relative rotation." The longitudinal slots have ylateral extensions Vor side recessesl adjacent veach end'thereof to'receiv'e the pins :and prevent A v Since the' carrier has relatively'free movement in the inner member it-'has been'easy for it Vto lbe inadvertently moved from the fside recess and along the longitudinal slot. This has been particularly true when the lipstick is being inserted while the carrier is in its Vouter position. Y

i the carrier'with a section of slightly reduced diameter and by providing therein a resilient friction projection adapted to engagefthe inner wall'of the cylindricalinnei member when the. pins are in 'the side recesses to resist unintentional rotative movement of the carrier therein. ,-Prefera# bly, the friction projection comprises at least a transverse unintentional longitudinal movement of the carrier at each f I end of its travel.

The lipsticky is carried by a cup-Shaped carrier 14 which has driving pins 15 projecting from opposite sides thereof. The ends of the vpins are-adapted'to pass through opposed longitudinallyextending slots-16, 17 formed in the side walls of the inner member.l The slots 161,17 extend-from a point spaced from the *closed end and extend longitudinally along the member. lPreferably,the slot 16 extends tothe free end `ofthe member as shown at 16C. At thevend of thedesired movement of the-carrier in retracted or projection positions, the slots are provided with lateralitextensions 16a, 16b,'17a,` 17b into which the ends of the pin can be moved to prevent inadvertent longitudinal movement from said positions. Y Y

i' Toxoperate': thecarrier from retracted to projected position, a sleeve 18 is rotatably mounted on the inner member and is preferably held in place by having a shoulder l18afat-'the outer end whichI is adapted to snap under `a cooperating shoulder 19a on the inner member', the opening 16c`at the end of longitudinal slot 164 providing sufcientresiliency. inthe outer end of the cylindrical membertopermit the sleeve to be assembled therewithnr.:

L The sleeve is provided with a pair of spaced helical grooves 20, 21 on the inner surface thereof, -as shown by portion having a convex outer surface which will guide tion projection by lateral and longitudinal ribs having convex outer surfaces with the projectionv aligned with the carrier pins. This projection will frictionally hold the carrier in position but will move along the 'slot and not interfere with the movement of the carrier during the normal movement of the carrier in the inner member by the rotating sleeve.

Other features and advantages of the invention will be apparent from the specification and claims when considered in connection with the accompanying drawings in which: 1.

FIGURE l is a longitudinal section of the device taken through the vertical slots.

FIG. 2 is a longitudinal sectional view of the device taken from the left of FIG. l.

FIG. 3 is a longitudinal sectional View of FIG. l look ing from the rightof FIG. 1.

FIG. 4 is a sectional view taken along line 44 of FIG. 3.

FIG. 5 is a side elevation of the novel lipstick carrier.

FIG. 6 is a view taken from the left of FIG. 5.

As shown in the drawings, the lipstick device comprises a cylindrical inner member 11 of plastic material having a transverse wall 12 at one end closing the member. The other end of the cylindrical member is opened and is adapted to receive a lipstick 13, shown in dot and dash the dot and dash lines in FIG. l, cooperating with the ends of the pin so tha-t upon rotation of thesleeve with respect to the inner member, the carrier will be simultaneously lifted at both' sides there-of by the groove to move the lipstick' uniformly in the cylindrical member.`

To prevent inadvertent movement of the carrier from the extensions'ln, 16b, 17a, 17b friction means is-pro has a portion 14a belowthepin sof -a reduced diameter t and has formed therein one or more friction projections 22 which are adapted, when in position as shown' in FIGS. -l, 3 and- 4, to frictionally engage the inner surface` ofthe cylindrical inner member 11. kIn the illustrated form of the invention, -there are .employed y-two friction projections '22 and they :arelocated in thel portion 14a below the-pins 15." While the projections may take m-any forms` itis at present preferredlto formeach of them by a trans` verserib 22a and a longitudinal rib 22b with each rib having a convex'outer surface'as shown in FIG. 6 with the -crossingpoint of the ribs projecting `slightlybeyond the diameterv of the carrier 14 Vso as to have good frictional engagement with the innermember. lBecause of the'shape and location of the ribs, v4they will ride over the edges 'of the sl-ot 16 as they are moved thereover by the carrier since the convex surfaces will smoothly guide the projection thereover, but because of the location of the projections the high point will be located within the slot 16, as shown in FIG. 2, and will not interfere with free movement of the carrier during retraction or projection of the lipstick.

While the present invention is applicable to all metal or a combination of plastic and metal lipstick devices, it is herein illustrated as being formed of plastic material because its structure is well suited to this material to produce an inexpensive lipstick device.

If desired, vent holes 25 may be provided on each side of the slot 16, as shown, to facilitate movement of the carrier.

While the inner member and sleeve can have one slot and groove respectively and the carrier have one drive pin, it is preferred to have a plurality of said elements in order to achieve a balanced operation.

Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.
